Encode file path to URL
Really helpfull when play with files having spaces an other bad name. Easy to store and access names and path in just a field while saving it in a file. This format (URL) is directly supported by nautilus and firefox (and other browsers)

Find files and calculate size of result in shell
Use find's internal stat to get the file size then let the shell add up the numbers.

Compare a remote file with a local file

SMTP Analysis
This works just as well for SMTP. You could run this on your mail server to watch e-mail senders and recipients: tcpdump -l -s0 -w - tcp dst port 25 | strings | grep -i 'MAIL FROM\|RCPT TO'

chroot, bind mount without root privilege/setup
PRoot is a user-space implementation of chroot, mount --bind, and binfmt_misc. This means that users don't need any privileges or setup to do things like using an arbitrary directory as the new root filesystem, making files accessible somewhere else in the filesystem hierarchy, or executing programs built for another CPU architecture transparently through QEMU user-mode. Also, developers can use PRoot as a generic Linux process instrumentation engine thanks to its extension mechanism, see CARE for an example. Technically PRoot relies on ptrace, an unprivileged system-call available in every Linux kernel. https://github.com/cedric-vincent/PRoot

Enable color pattern match highlighting in grep(1)
This will affect all invocations of grep, even when it is called from inside a script.

ssh autocomplete
Stop tormenting the poor animal cat. See http://sial.org/howto/shell/useless-cat/. Edit: replaced $ sort | uniq by $ sort -u
